8 Claims. (Cl. 139-291) This invention relates to improvements in wire looms.

In weaving long twisted loop pile fabrics on a wire loom, the twisted loops become intertwined with adjacent loops which is objectional. Under present methods the multi-ply pile warp yarns, each of the plies of which is slack twisted, are raised over a series of pile wires inserted in the woven fabric to form transverse rows of pile loops and as the wires are successively withdrawn the released loops will become twisted forming weftwise rows of twisted loops. During the twisting of the loops, some of the loops become intertwined with adjacent loops and must be separated after the fabric is woven. It is an object of the present invention to provide an attachment for wire looms which will maintain the loops in separate relation when released from the withdrawn wire without interferring with the twisting of the individual loops.

Briefly, the attachment comprises a bar supported above the pile surface of the woven fabric having its forward edge in parallel close relation to the first wire of a series with the forward edge in pressing engagement with the loops on the wire so that when the wire is withdrawn and the loops released they will be held by the bar in separate spaced relation and the individual loops-may twist without becoming intertwined with adjacent loops.

Other objects and advantages of the invention will be apparent during the course of the following specification.

In the accompanying drawings, forming a part of this specification, and in which like numerals are employed to designate like parts throughout the same,

Fig. 1 is a fragmentary top plan view of the attachment applied to a wire loom,

Fig. 2 is a section taken on line 22 of Fig. l, and,

Fig. 3 is a fragmentary perspective view of the same.

Referring to the drawings, the numeral 5 denotes the pile wires of a conventional wire loom which are successively inserted in sheds of pile warps 6 which are of multi-ply structure in which each ply is first slack twisted and then brought together and over-twisted. After insertion of the usual weft threads 7 the fabric is beaten-up to form rows of pile loops 8 on each of the wires. The number of wires in a series may vary and after the desired number are inserted, the first wire of the series is withdrawn and re-inserted in a shed following'the last wire of the series. In the present instance the wires 5 are of such height as to form relatively long loops.

The attachment forming this invention comprises a fiat bar 9 extending transversely of the loom which is supported above the pile surface of the woven fabric 10 by a series of arms 11 which may be angle bars. One end of each of the arms 11 is attached to the top of bar 9 by a bolt 12 and the opposite end is supported by a bracket 13 attached to a transverse channel bar 14, forming part of the loom, by a bolt 15. Each bracket 13 has a U-shaped portion 16 which engages over a flange of the channel bar 14 and flanges 17 along its longitudinal edges between which the ends of arms 11 are seated. A bolt 18 extending through the arms 11 and a slot 19 formed in the brackets 13 adjustably secures the arms to the brackets Cir 2,790,466 Patented Apn. so, @1957 sinay be iongttuii ally adjusted 0' move the arena edge o f bar9 intoc'd'ntact with the loo s on the first pile wire of the series. The bar 9 is positioned in close spaced relation to the pile surface of the fabric so that when the wire adjacent the bar is withdrawn releasing the loops the forward edge of the bar holds the loops in separate relation without preventing the loops from twisting. As the fabric is pulled forward the'twisted loops pass under the bar being pressed down flat upon the surface of the fabric until they pass beyond the, inner edge of the bar. The pile wires 5 are held close together and against the forward edge of the bar 9 by a series of hooked arm 20, shown in dotted lines, that engage over the last inserted wire of a series to hold the wires in posinon.

In operation, the forward edge of the bar 9 presses against the base of the loops formed'on the first wire of a series and when the wire is withdrawn and the loops released, the bar holds the loops in separate relation but the individual loops are free to twist but will not become intertwined with adjacent loops, so that each of the twisted loops remain separate and apart from adjacent loops. The attachment is designed for attaching to a conventional wire loom without alterations and may be readily adjusted to properly position the bar 9 with respect to the first wire of a series.

Having thus described our invention, we claim:
